title Indexer — Pair A publie, Pair B publie (handleNodePublish → DHT)

participant "Node A" as NodeA
participant "Node B" as NodeB
participant "IndexerService (partagé)" as Indexer
participant "DHT Kademlia" as DHT

note over NodeA: Après claimInfo ou refresh TTL

par Pair A publie son PeerRecord

note over DHT: DHT contient maintenant\n"/node/DID_A" et "/node/DID_B"
